This document discusses various immunohistochemical markers that can be used to help identify different types of cancer cells found in lymph nodes. Some common markers mentioned include AE-1/AE3, CAM5.2, CK7, CK20, Calretinin, EMA, HMB45, Inhibin, Melan A, Mucin, PIN4, PSA, S100, SYN, and Vimentin. These markers can help pathologists determine if cancer has spread to lymph nodes and what type of cancer it may be.
